| Abstract:We took safflower varity farm,‘B 1’‘1 3’‘3 10’ strains as materials to study the effect of temperatures （20,25,30 and 35 ℃）on safflower sprouts’ biological characteristics and effective components. The results showed that the highest seedling emergence rate of safflower seeds were 95.67%,90.00%,99.00% and 96.33% when the test temperature was 25 ℃, and the growth of safflower sprouts were best, the fresh mass of single reached maximum for 0.41, 0.41 , 0.49 and 0.45 g, respectively. One hundred plants biological yields were 41.00, 37.49 , 45.56 and 37.40 g, respectively. One hundred plants net production were 32.79, 31.08, 36.84 and 29.84 g respectively.However, at a temperature of 20 ℃,mass fractions of flavonoid and HSYA A were highest of 24.72 and 19.05 mg/g,mass fraction of polysaccharide increased, mass fraction of flavonoid and HSYA A in safflower seedlings decreased with the increase of temperature. The appropriate range of safflower sprouts’ growth was 20 ℃-25 ℃. |
